Three days later, Yun Tianyu left Quicksand City under the Heavenly Family's Six Great Dao Immortal Master, the Ran Family Master, and Zhuang Ziqi Gong, who made him feel extremely favorable.

Leaving Quicksand City, Yun Tianyu immediately took out the communication bead and sent a message to Qian Ruxue, who was sitting in Xisha City, and asked her to go to Tiantang City, a major trading city controlled by the Heavenly Family, to join her.

The reason why Yun Tianyu wanted to go to Tiantang City was because he learned from the Heavenly Family's Six Great Dao Immortals that in order to enhance their strength, the Heavenly Family secretly held a secret trade fair in Tiantang City, and some precious and rare treasures appeared.

And Yun Tianyu has a lot of useless treasures, and he can just trade some treasures that are helpful to him through the secret trade fair held in Tiantang City.

"Dragon Turtle, what type of weapon do you like?" asked Yun Tianyu softly on the way to Tiantang City.

"I love axes, and the heavier the axe, the more I like it. The burly dragon turtle said loudly.

"Axe, good. If there is a high-grade axe in the auction held by the Heavenly Family, I will help you exchange it for one to increase your strength. Yun Tianyu nodded lightly and promised.

"Thank you, Childe!" said the dragon turtle gratefully.

In about three days or so, the fast-flying Yun Tianyu and the dragon turtle flew to the sphere of influence of Tiantang City, because Tiantang City is a big city mainly controlled by the Tianjia family, and it is heavily guarded, so Tiantang City has not been harassed by the Hai family, and the entire Tiantang City is still very lively and orderly.

Since the Xisha City guarded by Qian Ruxue was farther away from Tiantang City than Liusha City, when Yun Tianyu and the Dragon Turtle came to Tiantang City, Qian Ruxue was still on the way.

"Let's go to the dragon turtle, let's take a look around this Tiantang City first, and see if there are any rare things for sale in this Tiantang City?" Knowing that it would take about half a day for Qian Ruxue to arrive through the transmission beads, Yun Tianyu and the dragon turtle followed the bustling crowd and walked into Tiantang City.

When Yun Tianyu and the dragon turtle walked along the bustling street to the center of Tiantang City, they found an eight-storey, pagoda-shaped pavilion that came into view.

At the entrance of the pavilion, there is a rectangular plaque, on which the three big characters of the dragon flying and the phoenix dancing in golden yellow font 'Tianxing Pavilion' are hung.

"Let's go to the Dragon Turtle, let's go to the Heavenly Star Pavilion to have a look, and see if there are any rare treasures for sale in this Heavenly Star Pavilion?" Yun Tianyu saw that the decoration of the Heavenly Star Pavilion was luxurious, and the level of the people entering and exiting was extremely high, so he became a little interested, and walked in with the Dragon Turtle.

"Two guest officers, I don't know what you need?" Yun Tianyu and the Dragon Turtle had just walked into the Heavenly Star Pavilion, and immediately a young woman wearing a big red cheongsam skirt and a pair of straight and slender legs walked over and asked with a professional smile.

"We need to buy some rare and precious things, I don't know if you have them for sale in Tianxing Pavilion?" Yun Tianyu asked straight to the point.

"Rare and precious things are naturally available for sale in my Tianxing Pavilion, but my Tianxing Pavilion has an unwritten rule, that is, heavy treasures with heroes, if the two guest officers want to buy rare and precious things, they must rely on their own strength to go to the eighth layer of my Tianxing Pavilion, otherwise you can only buy treasures that match your strength. The young woman whispered.

"I don't know what kind of strength is needed to walk to the eighth floor of the Heavenly Star Pavilion?" Yun Tianyu showed a faint smile and asked with great interest.

"The eighth layer of my Heavenly Star Pavilion needs to reach the strength of the third-level Dao Immortal realm or above before I can break the entrance ban and enter it to trade. The young woman said in a pleasant voice.

"Level 3 Dao Immortal! Okay, we know, let's try it. "Although Yun Tianyu only has the strength of the first-level Dao Immortal Realm, the Origin Space-Time Technique he has cultivated is far superior to the ordinary Dao Technique, and with the help of the Weather Origin Particles formed in his body, Yun Tianyu is confident that he will break through the eighth-layer entrance ban of the Heavenly Star Pavilion.

"Those two seniors, please come here. Hearing that Yun Tianyu and the Dragon Turtle wanted to ascend to the eighth floor of the Heavenly Star Pavilion, the young woman's gaze at them immediately changed, and even the title changed.

"Hmm!" Yun Tianyu nodded slightly, followed the young woman who gently shook Qianqian's slender waist, walked up the circular stairs, and walked towards the top of the Heavenly Star Pavilion step by step.

When Yun Tianyu and the Dragon Turtle walked to the junction of the first and second layers, they found a vague prohibition blocking their progress.

"Buzz!" Seeing the prohibition appear, Yun Tianyu and the Dragon Turtle bypassed the young woman who had stopped, and walked through the prohibition very easily and walked to the second floor of the Heavenly Star Pavilion.

"The two seniors, the juniors are weaker, so I won't accompany the two, I hope the two seniors can buy satisfactory treasures in my Tianxing Building. When Yun Tianyu and the Dragon Turtle passed through the prohibition on the second floor of the Heavenly Star Pavilion, the young woman did not follow them, and said in a soft voice.

"Hmm!" Yun Tianyu nodded, took out more than a hundred sea crystals from the Lei Ze ring, ignored the prohibition of the second layer of the Heavenly Star Pavilion, and rewarded the young woman with a happy face, and continued to walk towards the top of the Heavenly Star Tower with the dragon turtle.

The power of the fifth-level Dao Venerable of the third layer of the Heavenly Star Tower could pass through, and it was impossible to stop the footsteps of Yun Tianyu and the Dragon Turtle, and the two of them easily passed through the prohibition and quickly climbed the Heavenly Star Tower.

When Yun Tianyu and the Dragon Turtle climbed to the sixth floor of the Heavenly Star Tower, they obviously felt that the power of the prohibition had increased by one level.

Seeing that the third-level Dao Immortal Peak Realm Dragon Turtle easily passed through the prohibition of the sixth layer of the Heavenly Star Tower, Yun Tianyu immediately controlled the Void Immortal Core to release a force of Void Immortal, which melted into the prohibition that blocked him, broke the prohibition through a hole, and walked towards the seventh layer of the Heavenly Star Tower.

"Master, can you break this seventh-layer prohibition?" The dragon turtle knew that Yun Tianyu only had a first-level Dao Immortal realm, so when the two of them came to the seventh-layer space prohibition, the dragon turtle was slightly worried.

"Don't worry, Dragon Tortoise, the space ban on the seventh floor of the Tianxing Tower can't help me. Yun Tianyu showed a confident smile, unleashed the power of the Void Immortal containing the Weather Origin Particles, and fused into the terrifying seventh layer of the Spatial Prohibition.

"Buzz!" Fusing the power of the Void Immortal that contained the Weather Origin Particles, the spatial prohibition on the seventh floor of the Heavenly Star Tower trembled slightly twice before it was broken, and Yun Tianyu passed through the prohibition and continued to walk with the dragon turtle towards the highest floor of the Heavenly Star Tower, the eighth floor.

"Golden Prohibition!" Walking to the side of the prohibition on the eighth floor of the Tianxing Tower, Yun Tianyu was blocked by a layer of golden prohibition, and the overflowing golden light was like a live fish, constantly flowing in the golden prohibition.

"Origin Space-Time Technique, Break the Forbidden!" Feeling a trace of pressure from the golden prohibition, Yun Tianyu immediately ran the Origin Space-Time Technique at high speed, and the power of the Void Immortal that released the amplitude power penetrated into the golden prohibition.

At first, fusing the power of the Void Immortal that fused the amplitude power of Yun Tianyu, the golden ban only trembled slightly, but when Yun Tianyu fused the hundred Weather Origin Particles in his body into the golden ban, the golden ban immediately broke a gap, and Yun Tianyu passed through the gap and ascended to the eighth floor of the Heavenly Star Tower.

And the dragon turtle saw that Yun Tianyu, who was in the realm of first-level Dao Immortals, could actually rely on his own strength to break the prohibition that only third-level Dao Immortals could break, and the copper bell showed a hint of admiration in his big eyes, releasing the peak power of third-level Dao Immortals, passing through the golden prohibition, and following Yun Tianyu into the top floor of Tianxing Tower.

"Welcome to the eighth floor of my Heavenly Star Tower, I don't know what treasures you need to buy!" When Yun Tianyu and the Dragon Turtle walked into the luxuriously decorated and very deserted eighth floor of the Heavenly Star Tower, an old man with snow-white hair and strength that had reached the realm of third-level Dao Immortals appeared in front of the two of them and asked lightly.

"I want to buy some talismans or high-grade Heavenly Beast talismans, I don't know if you have them on sale in Tianxing Tower?" Yun Tianyu glanced at the white-haired old man and asked politely.

"Please forgive the old man's clumsiness, I feel that Your Excellency's strength does not seem to have reached the third-level Dao Immortal Realm!" Just when Yun Tianyu proposed to buy a talisman or a high-grade Heavenly Beast talisman, the white-haired old man vaguely sensed Yun Tianyu's true strength and asked in some surprise.

"Why, can't you enter here to trade if you don't reach the third-level Dao Immortal Realm?" Yun Tianyu asked with a smile.

"Of course not, as long as you can break through the ban on the eighth floor of my Heavenly Star Building and enter here, you can trade, I am just very interested in Your Excellency's cultivation method, and I have no other meaning. ”

"Okay, let's get down to business, my Heavenly Star Pavilion has three powerful runes for sale, but except for the lowest-level runes that can be purchased with sea crystals, we can only exchange the medium-power runes and the highest-powered runes for treasures. The white-haired old man introduced softly, "I don't know what level of treasure can be exchanged for the most powerful talisman!" Yun Tianyu asked with great interest.

"The highest-level talisman of my Tianxing Tower, which was refined by our landlord with great effort, is called the Tianxing Rune, once used, it can summon a large number of falling meteors out of thin air, and if you are caught off guard, you can severely damage the third-level Dao Immortal master. And if you want to exchange for a Celestial Star Talisman, you need at least a medium-grade Celestial Weapon or some runes of the same level. The white-haired old man gave a detailed introduction.

"A medium-grade celestial weapon can be exchanged! I don't know how many celestial talismans can be exchanged for a medium-grade celestial artifact. Yun Tianyu, who was carrying dozens of medium-grade celestial weapons, asked softly.

"The Celestial Star Talisman is extremely powerful, so a medium-grade celestial artifact can only be exchanged for one Celestial Star Talisman. The white-haired old man said lightly.

"I wonder if you can take out a Celestial Star Talisman and let me see how powerful it is?" Yun Tianyu pondered for a moment and proposed.

"Of course you can!" As he spoke, the white-haired old man took out a talisman sealed with the power of a powerful star and handed it to Yun Tianyu.

When Yun Tianyu released the soul power of the third-level Dao Immortal Realm and penetrated into the Heavenly Star Rune, he clearly felt the power of the Heavenly Star Rune, confirming that the white-haired old man had not deceived himself.

"I am very satisfied with the power of this Heavenly Star Rune, and I think the Heavenly Family is in great need of high-grade Heavenly Weapons at this time, so let's do it, I am willing to exchange ten medium-grade Heavenly Weapons for twenty Heavenly Star Runes, I don't know if your Heavenly Star Pavilion is willing to do this business?" After testing the power of the Heavenly Star Rune, Yun Tianyu pondered for a moment and spoke.

"No, no, no, it's a loss for us to exchange it like this. Although the white-haired old man had a strong interest in the ten medium-grade celestial artifacts proposed by Yun Tianyu, the value of the Heavenly Star Talisman was indeed very high, which made the white-haired old man refuse.

"Since that's the case, then forget it, anyway, with our strength, the Celestial Star Talisman is indeed of limited help to us. Yun Tianyu showed a faint smile and said in a gentle voice.

"Wait! The white-haired old man saw that Yun Tianyu had given up the exchange, and immediately opened his mouth to persuade him.

"Yes, but don't delay us too long, we have important things to do. Yun Tianyu nodded lightly and said.

"Don't worry, you won't be delayed too much. After saying that, the white-haired old man left in a hurry.
